http://en.wikipedia.org/wiki/Archimedes#The_Archimedes_Heat_Ray http://en.wikipedia.org/wiki/Archimedes#The_Archimedes_Heat_... Two millennia or so. Power generation has always been applying new ways to boil water (save wind and hydro).

Actually I misconstrued what the design was. I thought the mirrors would project a higher concentration of sunlight onto a traditional solar panel (except one designed to accept much higher input/density), thus saving the cost of making many panels and many periodic replacements. Mirrors are presumably cheaper and/or more durable than solar panels.
